Sorry, wrong ship. Most activities are geared to grown-ups on Marina, and there's no day care center, teen club or arcade to keep the younger ones occupied. That said, on a holiday weekend cruise to the Caribbean, we saw a number of school-age kids and younger adults traveling with their families. The pool, free milkshakes and port adventures are the attractions for this age group, so don't be afraid to take self-entertaining, well-behaved children on a cruise; just know the ship generally skews older. The library does have a small children's section.
